2. Claims: (Cl. 15=23*) This invention relates to hand operated.

More specifically, the invention proposes the A" further object of the invention is to providea small hand size power driven tool adapted to receive rotatablebrushes; buffers orother means For further comprehension of the invention, and of the objects and advantages thereof, ref-- erence will'behad to thefollowing description-and accompanying drawings, and to the appended claims in' which the various novel featuresof the invention are more particularly set forth;

In the accompanyingdrawing forming a material-part of this disclosure:

Fig. 1 is a sectional View of. a. power driven brushing tool constructed'in accordance with this invention,taken:ontherlinev I -.l of Fig. 3, parts being shown in full.

Fig. 2 is a plan view of the tool.

Fig. 3 is a side elevation ofthe tool;

Fig. 4 is a section on the line 44 of Fig. 2.

5 is a view similar to Fig.1 showing a tool constructed in accordance-with a modification" of this invention.

Fig. Si is. aplan-view of a buffer that may be employed with-the tools shown inFigs. 1-5.

The tool shown in Figs. 1-4, according to this invention includes a body l0 which consists of a handle II, a support l2 integral with the handle, a hood I 3 extending from the support and a support Hi at the other end of the hood. The body It! is preferably made of several pieces secured together, as shown. For instance, the handle H and support l2 may be made of a single piece of wood. The support I4 may be made of another piece of wood. The hood i3 may be made of thin sheet metal secured to the supports 12 and Hi by screws l5. Other kinds of material may, of course, be employed if desired.

Handle ll has a central chamber iii in which is housed a small electric motor H, which is shown diagrammatically in Fig. 1 and may be a well known type of motor such as is used in small electric hand drills. A bore it extends from chamber It through support l2 and a bushing [9 new and usefulimprovements in apower driven rotary utility tool-f for cleaning, polishing; bufifi'ng or the like, and" more particularly tosuch a tool adapted tobe 2,. is disposed in this bore. her that the other side of motor H andhas a centralborezi thnoug-h which passes an electric cord 22 supplying current tothe motor Hi Plug 20 may be removably secured to the handle in any desired manner so'that'it mayberemoved when it is desired." to service or repair the motor H.

Alignedrecesses 23 are formed ineach-side of sup--- ports i2 and M, and bushings- 24 are secured 26? Bin 25' has opposite-side openings" 2''! and 28 anda bottomwa-IFZQ havinga'n' opening 30 closed by a hinged and latched door 31. The interior ofithe-b'in is partitionedby a wall-32, formed by folding inward a" portion of the top wall of the bin, into two chambers 33 and 3'4", opening 21 opening into chamber 33andopening 28 opening into chamber 3!. The top edge'of opening 2'1 is curved outwardly forming a deflector 35 and-the bottom edge of opening 28 is curved outwardly forming a deflector 36.

i A shaft 3"l is journ'al-led in bushing 19; Shaft 3 atone end is connected to the armature not shown, of the motor IT- and at the other end a' gear seis secured to-shaft- 3-1. This gear is'disposed" in the space between the adjacent end of the bin- 25 andthe support I2-. The bin may form means preventing shaft}? from becoming operative'ly disassembled from'motor H. A hollow shaft 39 is journall'ed in each of they bushings, 2 t" andia gear 40 issecuredto each of these shafts and meshed with gear 38 to be driven thereby. A brush ll is disposed on each side of bin 25, each brush having one end disposed inside the adjacent hollow shaft 39 and secured thereto by a set screw 42 and its other end freely disposed in the aligned opposite bushing 24 supported in support M. The end of the brush disposed in bushing 24 may be rounded in any well known manner, as by building up with weld metal, or it may have a small sleeve forced on it, which sleeve acts as a journal in the bushing 24.

The operation of this form of device is as follows:

The electric motor rotates the gear 38 and thereby the gears 40, which rotate the brushes ll. The brushes 4| may be employed for instance, to brush clothing. They rotate in the same direction and as each brush passes its deflector 35 or 36, as the case may be, it throws the dirt or dust A plug 2 0 closes cham 3 it has collected into the bin 25. When the bin is filled, it may be emptied through the door 3|. Wall 32 prevents the dust being thrown in the bin from one opening from passing out through the other opening.

The tool described may be used for many purposes such as for brushing clothing, furniture, automobil upholstery and so forth. It has particular adaptation for getting into small places and for being employed as a hand tool facilitating many household tasks. Its operation promotes sanitation in that all dust or dirt removed from an article is collected in the bin and prevented from blowing around where it can be breathed in by the person operating the tool.

When used to brush fabrics, soft brushes may be employed. However, the tool may also be employed with hard brushes for cleaning pots and pans, walls and so forth. It may also be used to shine shoes and for polishing wax. If desired, the brushes may be replaced with buffers such as the buffer 43 shown in Fig. 6. The tool may then be employed for cleaning windows, mirrors, and the like.

The brushes may easily be removed from the tool for cleaning by taking out the screws l in support I 2 and moving support l4 away from support I 2, gears 40 staying with the brushes 4i when they are removed from the tool. If it is desired to replace the brushes, with new brushes or with buffers, they may be removed from the gears 49 by removing the set screws 42.

The invention is applicable to rotary brushes and buffers for employment with water, cleaning fluid or other liquids. In such case, as the liquid might interfere with the electric motor, it is contemplated to employ instead a. flexible shaft. Such a construction is shown in Fig. 5 wherein the tool is distinguished from the tool shown in Figs. 1-4 in that the shaft 31 is driven by a flexible shaft 44 which extends through the bushing l9 disposed in the handle ll. In other respects this tool is similar to the tool of Figs. 1-4.

The brushes 4| of the form of the invention shown in Figs. 1 to 4 or the brushes 4 l in the form of the invention shown in Fig. 5 may be replaced, when desired, by rotary buffers, one of which is shown at 43 in Fig. 6. To substitute buffers of the type shown in Fig. 6 for the brushes, the utility tool is disassembled to free the brushes in the manner previously described for freeing the brushes to facilitate cleaning thereof.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the pre- 4 cise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention what I claim as new, and desire to secure by United States Letters Patent is:

1. A brush comprising a handle having a recess, driving means disposed in said recess, a hood secured to said handle and open at its bottom, said hood having longitudinally curved sides, two spaced rotatable cylindrical brushes in said hood, one adjacent each of said curved sides, gear means connecting said brushes with said driving means, a dust bin disposed between said brushes, said dust bin having a curved side portion adjacent each of said brushes, each of said curved sides having an opening adjacent its correlated brush and above the bottom of said dust bin, said dust bin further having a bottom wall between said side walls, said bottom wall being provided with an opening, a hinged door for said bottom wall opening, and a partition in said dust bin between said side walls and extending from the top of said dust bin to adjacent said door for preventing dust from blowing out of its side openings, said brushes extending below said hood.

2. A utility brush comprising a handle and a hood portion connected therewith, a pair of spaced parallel brushes mounted for rotation in said hood, a. receptacle for collecting dust secured on said hood and disposed intermediate said brushes, said receptacle having a pair of openings formed therein, said openings comprising dust admission ducts to the interior of said receptacle, each of said openings being positioned adjacent one of said brushes, a. baflle plate mounted in said receptacle and positioned intermediate said openings, means for removing dust collected in said receptacle comprising an opening formed in said receptacle and a closure member therefor, and driving means connected with said brushes.
